Imagene Isoflow Reagent Dispenser

The IsoFlow™ Dispenser is an integrated system which precisely dispenses liquid reagents in lines onto membranes for the production of immunochromatographic diagnostic test strips. IsoFlow™ accurately and repeatedly applies a continuous reagent line onto the solid medium.

Digital Control IsoFlow™ uses digitally controlled positive displacement pumps in combination with precision nozzles to develop a uniform stream of reagent. The nozzles are moved over the membrane using a digitally controlled carriage resulting in a fine line of reagent on the membrane with an inherently uniform reagent density (uL/mm).

Optimization IsoFlow™ simplifies the development, optimization, and manufacture of diagnostic test strips by allowing the operator to easily vary the dispense rate by entering the desired value (in uL/mm) into IsoFlow’s™ hand-held terminal. There is no need to “recalibrate” between settings.

The key to the LCP technology is the flexible nozzles. Variations in the membrane thickness cause the nozzles to flex a little more or less so that the contact with the membrane is always maintained. The contact pressure is so low that there is no significant mechanical stress on the membrane.

Features

Dispense 1 to 8 different reagents simultaneously. Each reagent dispensed is controlled independently.

Internal vacuum source to hold down membrane. No external air or vacuum required.

Low dead volume – approximately 100 uL of which 60 uL can be recovered when dispensing is complete.

Small foot print (33 cm wide by 66 cm long) and light weight (13 kg).

A-Point Guillotine Cutter

The Guillotine Cutter is designed for cutting assembled test cards into finished strips for packaging and sale. Simply designed and easy to operate this machine is ideal for R&D and production applications. The operator can easily adjust by using the interface. The Guillotine Cutter is a cost effective piece of equipment every production facility should include as a requirement.

The Guillotine Cutter is produced for small to medium volume manufacturers. Cutting volumes can easily exceed 50,000 strips per day. The blade is designed to be re-sharpened following half a million to a million cuts so an extra blade is recommended to avoid down time.

A-Point Assembly Roller

The Assembly Roller is a simple and durable machine designed to assist in the closing of plastic cassettes.

In a high paced production environment repetitive stress on assembler’s hands and wrists can hinder production and result in loss of volume and down time.

By allowing the assembler to simply put plastic halves together and drop them through the sealing wheel, the Assembly Roller removes this troublesome activity from the manufacturing process. This ensures higher sealing consistency and reduces stress on employees.

A-Point Rotary Cutter

Volume When markets are established the need arises to increase production volume. With throughput levels in excess of 100,000 tests per day and negligible variation from test to test, a Rotary Cutter is an all important manufacturing upgrade.

Customize A-Point’s Rotary Cutters are built to order. Your exact cutting width and product material choice is carefully considered in building your Rotary Cutter. Special design considerations are also available including card feeders and packaging shoots.

Cost Effective A-Point Technologies recognizes the need to keep overhead costs down especially for large volume manufacturers. The A-Point Rotary Cutter is a clear choice compared to similar Rotary Cutters offered by other manufacturers.

A-Point Semi Automated Laminator

Working with A-Point Technologies, a proven partner to high volume diagnostic test manufacturers, Arista Biologicals Inc. is proud to offer the Automated Laminator. This equipment will decrease production time and remove the need to individually handle sensitive and easily damaged membrane.

Laminator can be modified to accept larger reel sizes and different card widths

Universal power supply either 110v or 220v

A-Point Reel to Reel Blocking and Conjugate Treatment System

The reel-to-reel blocking system is used for the soaking of conjugate and sample pads in solution. This modular system offers flexibility and customization by the user. It can also be used to dispense conjugate onto pads. This system features both in-line and off-line dryers and a convenient rewind system.

Imagene Reel to Reel Dispensing System

The IsoFlow™ Reel-to-Reel Dispenser precisely dispenses liquid reagents in lines, onto reels of membrane, for the production of immunochromatic diagnostic strip tests. The membrane is dried in the integral drying tower before it is re-reeled. The IsoFlow™ Reel-to-Reel Dispenser is designed for large-scale production and can produce 30 to 60 thousand tests per hour.

Digitally controlled positive displacement pumps in combination with Imagene’s LCP (Low Contact Pressure) nozzles ensure consistent lines of the highest quality. When configured with Imagene’s atomizing nozzle the system can be used for treating conjugate pads with release buffers and colloidal gold conjugates.
